Pardon the prefixes from Docker, #20 simply means this was the 20th build step in my Dockerfile and the number after it is a timestamp.

I guess the warnings here are benign ...?

Hmm, I was able to log in and play around with it for a while but then it froze. Maybe I touched something I shouldn't have?

The last things I can see on the console are

205:M 20 Oct 2021 21:06:05.211 * 100 changes in 300 seconds. Saving...

205:M 20 Oct 2021 21:06:05.314 * Background saving terminated with success

It happened again, this time without anything interesting on the console. The site icon in the browser tab is replaced with a spinner, I can still click open menus but attempting to select something in them or otherwise clicking on anything doesn't navigate away from the page where I was when it happened. But it looks like there are probably just a few routes which trigger this. For example, just now, it clearly happened when I clicked http://localhost:5000/dev/request-log/user/1 and I think the earlier occurrences were also related to clicking on dev stuff related to logging or dumps.
